Steam at a pressure of 10 bar and 0.9 dry dis charges through nozzle having throat area of 450 mm?. If the back pressure is 1 bar. Find, (1) Final velocity of the steam (ii) Cross-sectional area of the nozzle at exit for maximum discharge.

Ex 1 // Isentropic flow of air in convergent nozzle is supplied from a large reservoir in which the pressure and temperature are 650 kpa and 350 k respectively. At a section in the nozzle where the area is 26 cm2 , the Mach is found to be 0.5, if the is nozzle discharged to a back pressure 270 kPa. Find the exit area and is the flow chocked?

A gas with flow rate of 100 MMSCFD of needs to be compressed from 800 to 8,000 psia. The inlet temperature is 90°F. How many stages are needed to compress the gas? Assume a 3% pressure loss between stages. Calculate the required HP. What type of compressor would you recommend? Assume n, = 0.9, and Em = 0.9. Yg = 0.62, k = 1.32.

Please solve asap!!!!!!??:;
